What is the difference between pstm on floating datum, and patm on final datum.
what is the theory behaind KPRET2D Modules, is it deal with input data(corrected to floating datum).
if yes then kindly explain why we use floating datum corrected data rather than final datum corrected data for PSTM.

My understanding is that the KPRET2D module currently does not take into account the elevation and depth of the shots and receivers. In which case you should correct the input to KPRET2D to a fixed datum. You'll also want to correct the velocity field to this datum. This can be done by using the shiftnmo utility in Claritas, there are more details on this utility in section 16.3.5 of the manual.
